Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - 1UR-FE STARTING

STARTER - INSPECTION

1. INSPECT STARTER ASSEMBLY
  • CAUTION:
  • As a large electric current passes through the cable during this inspection, a thick cable must be used. Otherwise, the cable may become hot and cause injury.
  • NOTICE:
  • These tests must be performed within 3 to 5 seconds to avoid burning out the coil.

Mount the starter in a vise between aluminum plates.

Perform a pull-in test.

Remove the nut and disconnect the lead wire from terminal C.

Disconnect the negative (-) terminal lead from the starter body. Check that the clutch pinion gear moves inward.


If the clutch pinion gear does not move inward, replace the magnet starter switch assembly.

Perform an operation test without load.

Connect the lead wire to terminal C with the nut.

Check that the starter rotates smoothly and steadily while the pinion gear is moving outward. Then measure the current.

  • Standard current:
  • 150 A or less at 11.5 V

If the result is not as specified, replace the starter assembly.


2. INSPECT STARTER ARMATURE ASSEMBLY

Check the surface of the commutator for dirt and burns.


If the surface is dirty or burnt, correct it with sandpaper (No. 400) or a lathe.


If necessary, replace the starter armature assembly.

Inspect the commutator for an open circuit.

If the result is not as specified, replace the starter armature assembly.


Starter - Inspection. 1UR-FE STARTING. Land Cruiser URJ200  URJ202 GRJ200 VDJ200

Using a vernier caliper, measure the commutator diameter.

  • Standard diameter:
  • 29.0 mm (1.14 in.)
  • Minimum diameter:
  • 28.0 mm (1.10 in.)
  • HINT:
  • Be sure to measure the commutator diameter at the ridges.

If the diameter is less than the minimum, replace the starter armature assembly.


Check the commutator circle runout.

Place the armature shaft on V-blocks.

Starter - Inspection. 1UR-FE STARTING. Land Cruiser URJ200  URJ202 GRJ200 VDJ200

Using a dial indicator, measure the circle runout.

  • Maximum commutator runout:
  • 0.05 mm (0.00197 in.)

If the commutator runout is more than the maximum, replace the starter armature assembly.


Starter - Inspection. 1UR-FE STARTING. Land Cruiser URJ200  URJ202 GRJ200 VDJ200

Using a vernier caliper, measure the undercut depth of the commutator.

  • Standard undercut depth:
  • 0.4 mm (0.0157 in.)
  • Minimum undercut depth:
  • 0.2 mm (0.00787 in.)
  • HINT:
  • Be sure to measure the commutator undercut depth at a cutout.

If the undercut depth is less than the minimum, replace the starter armature assembly.


3. INSPECT STARTER BRUSH HOLDER ASSEMBLY
Starter - Inspection. 1UR-FE STARTING. Land Cruiser URJ200  URJ202 GRJ200 VDJ200

Using a vernier caliper, measure the brush length.

  • Standard length:
  • 14.4 mm (0.567 in.)
  • Minimum length:
  • 9.0 mm (0.354 in.)
  • HINT:
  • Be sure to measure the brush lengths at the protrusions.

If the brush length is less than the minimum, replace the starter brush holder assembly.


Inspect the load of the brush spring.

Starter - Inspection. 1UR-FE STARTING. Land Cruiser URJ200  URJ202 GRJ200 VDJ200

Take a pull scale reading immediately after the brush spring separates from the brush.

  • Standard spring load:
  • 22 to 27 N (2 to 3 kgf, 5.0 to 6.1 lbf)
  • Minimum spring load:
  • 14 N (1 kgf, 3.1 lbf)

If the load is less than the minimum, replace the starter brush holder assembly.


4. INSPECT STARTER CENTER BEARING CLUTCH SUB-ASSEMBLY

Check the gear teeth of the planetary gears and starter center bearing clutch for wear or damage.


If any planetary gear is damaged, replace the planetary gears. If any teeth of the starter center bearing clutch are damaged, replace the starter center bearing clutch sub-assembly.

Starter - Inspection. 1UR-FE STARTING. Land Cruiser URJ200  URJ202 GRJ200 VDJ200

Check the movement of the clutch pinion gear.

Rotate the clutch pinion gear clockwise and check that it turns freely. Try to rotate the clutch pinion gear counterclockwise and check that it locks.
